WARNING
The parking brake may not be sufficient to
secure the vehicle on uphill and downhill
gradients. A loaded vehicle or a vehicle with
trailer/semitrailer may roll away. There is a
risk of an accident.
In the control position, check whether the
parking brake alone can hold the entire vehi-
cle. The tractor unit and trailer/semitrailer
should normally be secured using the park-
ing brake and wheel chocks.
In the check position, the vehicle/tractor/
trailer combination is only held by the spring-
loaded brake cylinder of the towing vehicle.
You can find further information about the
parking brake of the trailer/semitrailer in the
manufacturer's operating instructions.
